WIND OWSCREEN.

Specification of :Letters Patent.

PatentedvO-ct. 7,1913.

Application filed October 26, 1911. Seral No. 656,914.

To all whom '25 may concern Be it known that l, RICHARD S. FOSTER, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented certain new and useful mprovements in lVindow-Screens, of which the fol lowing is a full, clear, and exact speci-fication.

r-lhis invention relates to window screens and has for an object to provide a device which will permit an amount 'of air and light to enter lan open window while obstructing a view of the inside of the .apartment 'from the outside. The device will also prevent .a direct current of air entering the open window.

The screen Vis so supported that the air from the open window may pass freely above and below it, the major portion of .the device standing clear of the window frame.

The various features of adjustabi'lity and adaptability will 'be outlined in the following description.

One lpracticable embodiment of the invention is illustrated vin the accompanying drawings, wherein- Figure l is a yfront view o'f the device, that is, a View from the side which will be directed inwardly of the apartment. Fig. 2 is a top plan view of the device applied to a window easement, thelatter .being shown in horizontal section; and Fig. 3 is a similar view showing the easement in lvertical section.

The screen 5, is a vision-obstructing screen and is preferably made of some material which will completely 4prevent persons looking through the screen and particularly from the outside. lt will be supported in such position relatively tothe window-frame or casing and of the wall that air from the open window may freely pass above and below it and the majorportion of the device stand clear of these parts.

The screen illustrated is made of fabric carried by a pair of frames 6, 7, which are shown longitudinally adjustable one toward Lthe other, that is, longitudinally lso far as they are concerned, ybut ina direction which will correspond when the device is in use with the width of the window, so that the screen maybe adjust-able to various widths of window. In some instances the 'screen will beso constructed that it will lpermit the circulation of 'a certain amount of air, but will break up and diffuse the direct air currents and at the same time obstruct the view.

'Supporting `devices 8, are shown carried by the respective ends of the `screen frames 6 Aand 7, and project laterally therefrom, preferably in a plane perpendicular `to lthe plane of the screen. These supports are designed to engage the easement of a window and are suficiently long to hold the screen away from `the window-frame Iand from the walls.

In the present illustration members 9 are provided for engaging ythe sash channels or ways of the window easement when the window `is open. In applying the dev-ice the sash will be raised, lthe members 9 inserted in the ways for thesash and Vthen the sash closed down vupon these members 9, which will securely hold the device in position. To enable the supports to be readily closed or folded up upon the screen when the 'device is not in use, these supports are shown hinged by suitable hinges l0, to the frames. The hinge kis shown secured Vto the outer side of the support and to the front of the 'frame so that the support may fold flat upon the screen when not in use, and when in use may 'fold so `that its end rests rupon the flat face of the back of the frame and is rigidly held in position by suoli engagement and the action of the hinge. It will be seen that in this position the strain will be borne by the screws in a direction transverse to their axes, so that the tendency to pull the screws out will be minimized. Sufficient elasticity is resident in the supports to permit the insertion of the members 9 into the sash-ways by springing the supports inwardly one toward the other. The elasticity will securely hold the screen in position whether or not t-he sash is moved into engagement with the members 9.

For the purpose of permitting the opening of the window less than the full height of the supporting devices, the supports are shown comprising top and bottom members 11 and 12, which are pivoted at 13 to the hinge-carrying portion 14 of the support. A pair o-f links 15, 16, somewhat after the analogy of a toggle will link the members 11 and 12 together. rlhe lower members 9 are shown extending below the supports a suiiicient distance to cause the support members 12 to clear the window sill when the members 11 and `12 are caused one to approach` the other. n

The easement-engaging Vmembers 9 are shown pivotally carried by the support members 11 and 12 to enable these engaging members to have'a close fit in the sash-ways and permit the movement of the members 11 and 12 one toward the other.

A guide 17, is provided for the pivot 18, which connects the links 15 and 16, and in this guide is shown a compression spring 19. By means of this elastically-pressed toggle the support will readily adjust itself to variations in the height of the window sash, so that the sash may be raised or lowered within the limits of the amplitude of movement allowed by the device without recourse to adjustment of the parts by hand. lf, however, it is desired to hold the top and bottom members 11 and 12 in some particular position of adjustment, the pivot 18 may be in the form of a set screw having a wing nut.

When the sash is lowered for closing the window opening, the position of the screen is shifted. lt is brought closer to the window and its bottomedge is lowered so that when a strong air current is directed through the window, the window may be partially closed and the-screen will lap over theI window and over the wall below the window to a greater extent than when the window is opened to the full limit of the device, and also the screen is placed closer to the window.

The supports will preferably hold the screen in a plane at a distance'from and parallel with the plane of the window. The distance o f the screen from the opening of the window may be adjusted. The member 1 20, carrying the easement-engaging members 9, may be adjusted longitudinally on the end members 11 and 12, and their adjustment may be secured by means of set screws 21.k ln some cases it is desirable to employ the screen 5, in connection with a netting screen, the framework of which may readily be seated in the recess 22 of the engaging members 9. Adjustable and removable end screens 23 may be swung on butt-hinges 24, and be held in their positions of adjustment by means of links 25 and set screws 26.

1t will be apparent that various changes may be made within the scope of the claims without departing from the spirit of the invention. Y

Having described my invention what l claim and desire to secure by Letters Patent is:

1. The combination with a vision obstructing screen, of a support hinged to each end thereof in position to fold flat over the face and within the area of said screen and into rigid engagement with the back so as to assume a position transversely thereof, and easement-engaging members carried by the support. Y

2. The combination with a screen, of a support therefor comprising a pair of laterally-extending members in pivotal connection with the screen, linkage after the analogy of a toggle connecting such members, a guide for the pivot connectingthe links together, and a compression-spring located in the guide and engaging the toggle for forcing the said members apart.

3. rlhe lcombination with a screen, of a support at the end thereof comprising a pairV of laterally-extending members, a pair oflinks pivoted to said members and to each other, a guide for the pivot connecting the links, said pivot being in the form of a set screw.

1. A window screen, a pair of laterally directed supports movably carried thereby, and grooved. easement-engaging members mounted upon supports for seating in the.

sash ways of the Casement and affording a seat for a screen frame.

5. The combination with a window screen, of a pair of supports carried thereby, each comprising a pair of laterally-extending members and links connecting the members of each pair so that lwhen said members are in position upon they easement andthe said members are caused to move one toward the other, the lower edge of the screen will be lowered, and when said members are caused to recede one from the other, the lower por-V tion of the screen will be raised, whereby when the screen is in position and the window is at its position of maximum opening,

there will be aminimum of lap of the screen over the window and the window sill, and when the window is at its minimum of opening there will be the maximum amount of lap over the sash and the sill.

6. The combination with a windowcasing and sash, of a screen, means for supporting the screen and engaging the easement in the line of movement of the sash and comprising members movable one toward the other upon the lowering of the sash, the screen being located in position to stand inwardly of the apartment and away from the sash and sill, leaving a free passage for air at In Witness whereof I hereunto set my the top and at the bottom, said screen and hand in the presence of two subscribing its supports being constructed and adapted Witnesses.

for overlapping the sash and the sill at a RICHARD S. FOSTER. greater distance When the sash is at its Witnesses:

minimum opening than When it is at its WM. C. DUNN,

maximum opening. CHAs. LYON RUSSELL.
